BED-SPRING.

SPECIFICATION forming part of Letters Patent No. 757,098, dated April 12, 1904.

Application filed April 221903.

To (LZZ whom it may concern.-

Be it known that we, J ONAS F. DIXON and THOMAS J. RIDGWAY, citizens of the United States, residing at Oarthage, in the county of Jasper and State of Missouri, have invented a new and useful Bed-Spring, of which the following is a specification.

This invention relates to bed springs, and

. has for its objects to produce a device of this character which will be simple of construction, efficient in operation, and one in which the individual springs will be securely connected with the bottom framework and will be firmly braced and strengthened at their tops.

To these ends the invention comprises the novel details of construction and combination of parts more fully hereinafter described.

In' the accompanying drawings, Figure 1 is a topplan view of a portion of a bed-spring constructed in accordance with this invention. Fig. 2 is a perspective view illustrating the manner of connecting the tops of the individual springs in pairs. Fig. 3 is a detailed perspective view of the bottom coil of one of the individual springs. Fig. 4: is a plan view of the modification. Fig. 5 is a perspective view of the same. Fig. 6 is a detail view of the same.

Referring to the drawings, 1 and 2 indicate, respectively, the main top and bottom frames, which are composed, preferably, of wire and are suitably spaced one above the other. The bottom frame 2 is provided with a series of longitudinal wire stringers 3, which are connected at their ends to the end bars of the bottom frame, and 4 indicates transverse stringers connected at their ends to the longitudinal bars of the bottom frame. These stringers at their points of intersection have secured to them the lower coils of the individual springs 5 of the fabric. Inasmuch as the lower ends of all of the individual springs are attached to the bottom frame of the structure in an identically similar manner, we will describe the connection of but one in detail in which the wire composing the coil is at the beginning of the formation of the latter, bent to form a vertical downwardly-depending finger 6,

Serial no. 153.815. (N0 modeh) stringer 3, then above the transverse stringer a, then beneath the longitudinal stringer, and, lastly, again above the transverse stringer, as clearly illustrated in Fig. 3. At the point of meeting of the stringers at the center of the coil the longitudinal stringer, which overlies the coil at diametrically opposite points, lies beneath the transverse stringer at the center of the coil. as indicated at 8. In this connection it is to be noted that lateral slipping of the bottom coil of the spring is entirely obviated, owing to its alternate engagement above and below the stringer-wires, while rotation in one direction is prevented by the finger 6 lying-in close contact with the side of the stringer-wire and in the other direction owing to the wire forming the coil being slightly bent at the point where it passes beneath stringer 3 to form a stop-shoulder 8.

In order, however, to further strengthen the connection and obviate rotation of the spring, a diagonal brace-wire or stringer 9 is employed, which passes beneath the bottom coil above the point of intersection of the stringers 3 and 4 and has its end wrapped around the coil at the point of overlapping of finger 6 therewith.

Each individual spring at its top terminates in two coils which occupy the same horizontal plahe. The inner of these coils 10 is spiral and merges into the outer coil 11, which is substantially rectangular. The inner coil 10 at a point diametrically opposite the point of merging into the outer coil is bent clownwardly in a vertical plane to form a recess 12 for the purpose which will presently appear.

13 indicates a longitudinal stringer which is connected at its ends to the end bars of the top frame 1. This stringer, which sustains the top coils 10 and 11 of the spring 5, is angularly bent in a horizontal plane, as at 14, to form a horizontal finger which projects into the recess 12 and above the wire of the coil 10, while the stringer adjacent to the finger 14: and at opposite sides thereof lies beneath the wire of the coil 10 and continues thence and overlies the wire of the coil 11.

The individual springs 5'are connected in pairs and mutually braced one from the other at the terminals of the transverse rows of springs by means of a connecting member 15, which is bent at suitable distances from its terminals to engage downward through the fingers 141 of the respective springs of the pair. The body portion of the connecting member lies above the outer coils 11 of the springs, while the wire forming the member after passing through the fingers 14: is bent back upon itself and lies in a horizontal plane beneath the wire of the coil and is again bent, as at 16, upward and around the same. From this construction it will be obvious that a strong and admirable fabric is produced in which the individual springs will be mutually braced one from the other, and consequent breaking down of the springs in practice is to a large extent obviated, and, further, it is to be noted that by terminating the tops of the individual springs with the outer rectangular coils 11 a more compact relation of the parts is obtained and a firmer support for the mattress is insured. The inner springs of the fabric are connected one to another, and the top coils 10 and 11 are sustained in the proper relative plane by bending the terminal or finishing stem of the wire at the completion of the coil 11, as at 17, and extending the same inward beneath the coils 10 and 11, then bending the same backward upon itself to form an arm 18, which is extended to the next spring of the series and has its terminal end bent to form a hook 19 for engagement with the finger 14 of the stringer 13 within the next adjacent spring, the arm 18 being arranged to overlie the coils 10 and 11 at the points 20 and 21, respectively, and be- I neath the wire at the termination of the coil 11, as at 22.

In the modification illustrated in Figs. 4 to 6 the recess which is formed in the top coil of the spring and which corresponds to the recess 12 of the preferred form is formed by bending the wire of the coil vertically downward, as at 23, while the finger 2 1, which is formed upon the stringer 13 and corresponds to the finger 14 of the preferred form, is bent to extend upward in a vertical plane above the coil in position to be engaged by the tie which connects the coils. Also in this form of the device each individual spring 5 terminates in a single upper coil of spiral form, and the tie connecting the coils is formed by bending a length of wire at the terminal end of the coil first inward, as at 25, for engagement with one of the inner coils of the spring, thence backward upon itself to form an arm 26, which extends in a substantially horizontal plane to the next spring, where it passes between the top coil 27 of the same and the underlying stringer 13, thence backward through the vertical finger 2 1 and recess 23, and is finally bent downward in the form of a finger 28, which engages the top coil of the spring at its outer side. It is to be noted that the inwardlyextending portion 25 of the wire lies beneath the inner coil of the spring with which it engages and that the arm 26 lies above said inner coil at the point 29 and beneath the outer coil at the point 30, thus obviating the liability of the wire forming the finger 26 being accidentally bent out of proper position.

From the foregoing it will be seen that we produce a spring-mattress which as a whole will be very strong and durable, one in which liability of the individual springs becoming broken down or displaced relative one to another is entirely obviated and one in which the springs will, owing to the improved manner of connecting them one with another, be firmly braced and strengthened, and in attaining these ends it is to be understood that we do not limit ourselves to the precise details herein shown and described, inasmuch as minor details may be made herein without departing from the spirit of the invention.

Having thus described the invention, what we claim is 1. A bed-spring comprising a plurality of individual springs, a stringer lying beneath and within the upper coil of the springs and bent to form a finger extending above said coil, and a connection between the springs, said connection being formed by bending the wire at the termination of the last coil of one spring first inward for engagement with one of its inner adjacent coils, then back upon itself to form an arm extending to the next spring, said arm being arranged to overlie the inner coil and to underlie the outer coil at the termination of the latter, the terminal of the arm being bent to form a finger for engagement with the finger of the stringer within the adjacent spring.

2. In a bed-spring, the combination with a plurality of individual springs each having at its top two coils lying in the same horizontal plane, the outer of said coils being of substantially rectangular form, and the inner coil provided with a recess, of a stringer extended beneath the coil and bent to form a horizontal finger which projects into said recess, and a connection between the springs, said connection being formed by bending the wire at the termination of the outer coil of one spring inward for engagement with its inner top coil, then back upon itself to form an arm ex- IIO tending to the next spring, said arm being arranged to overlie the inner coil and to underlie the outer coil at the termination of the latter, the terminal of the arm being bent to form 5 a finger for engagement with the finger of the stringer within the adjacent spring.

In testimony that we claim the foregoing as our own We have hereto affixed our signatures in the presence of two witnesses.
